1 Claim.
The present invention relates to shutter struc
ture particularly designed for attachment for
ward of the radiator grille fronts of automobiles.
More speci?cally, the invention is primarily
(n concerned with shutter structure of the type in
(Cl. 189—61)
and I2. The outer contour of the sections in
practice may conform to the inner marginal
edge of the radiator shell M which projects for
wardly of the radiator I6 or it may overlap the
same. As illustrated the shutter is ?xed to the
grille made up from vertical slats IS‘ with hori
stalled as an accessory and used only during the
winter months. In this type of shutter structure - zontal supporting members 20 and 22. As shown
attractiveness, compactness, low cost of produc
the sections l0 and [2 are positioned upon oppo
tion, ease of installation and removal, and reg
site sides of a centralornamental vertical bar
ulation are matters of principal concern.
According to the present invention the shutter
structure comprises two entirely separable sheet
metal body sections each capable of being at
tached to the radiator grille and to cover one
half the ventilation area forward of the radiator
as de?ned by the outer surface of the grille.
Each of these sections is preferably held in posi
tion upon the outer surface of the grille through
snap-on attachment clips carried upon the rear
side of each section and engageable with parts
of the grille structure. For regulating the air
flow through the shutter sections, each section is
provided with adjustable openings which may be
under the control of pivoted shutter slats, louvers,
dampers, or the like. In the preferred form of
the invention as herein illustrated the openings
in each shutter section are regulated by an ax
ially slidable damper located on the underside
of the shutter sections and directly adjacent the
LO 0 radiator grille structure. As it is desirable to reg
ulate the opening in the sections simultaneously,
simple means have been provided for intercon
necting the dampers even though the sections
are angularly disposed to each other necessitated
3.‘, by the pointed or stream line contour of the ra
diator grille.
In the drawings
Fig. 1 is a front elevational View showing the
shutter in position, parts of the shutter being
40 shown broken away,
Fig. 2 is a side elevational View of the shutter
24, part of the grille structure, and'each section
is shaped at 26 and 28 to accommodate the em
blem 30 of the automobile manufacturer which
is carried by the grille structure.
Positioned upon the rear side of the sections
IE! and I2 are dampers 32 and 34 supported for 16
vertical slidable movement‘ upon pin and slot
connections 36 (see Fig. 3). The dampers 32
and 34 have spaced openings 38 which conform
in shape and spacing to the openings 40 in the
sections [0 and 12. In Fig. 1 the dampers 32 and 20
34 are shown in partial open position; the open
ings'38 of the dampers 32 and 34 being in full
alignment With the openings 40 when the damp
ers are slid upward to the full limit of the pin
and slot connections 35 and completely closing 25
the openings 40 when slid downward to the lower
limits of the connections 36. Flat springs 42
may be inserted between the sections Ill and I2
and their associated dampers 32 and 34 to pre
vent any rattle.

To enable the shutter sections I0 and I2 and
their associated parts to be quickly applied and
removed from the grille, we preferably employ
a plurality of spring detents 44 which are an
chored to the rear side of the sections I0 and 35
I2. These detents 44 are so positioned as to
come between the slats l8 of the grille and upon
downward movement of the sections l0 and [2,
which are separately applied to the grille, the
detent will snapback of the horizontal rein 40

68 is designed to be clamped to the instrument
panel by an adjustable clamping screw ‘#2. The
operating shaft 14 which is rotated to open and
